[Phonecardiographic features of atrial septal defect].

چکیده
The heart sounds of 20 patients with uinecomiplicated atrial septal defect have been analyzed, and the deviations from a normal control group were noted. Following complete closure of the defect 11 patients have been restudied, and the changes produced in the heart sounds by closure of the defect are discussed. By comparison of pre-operative and postoperative heart sounds and electrocardiograms it has been possible to ascribe some abnormalities of the heart sounds to the presence of the left-to-right shunt, and some to the presence of delayed electrical depolarization of the right ventricle.

Introduction: Atrial Septal Defect (ASD) is one of the most common congenital heart diseases during childhood. Today, ASD closure is done by occlutech device via cardiac catheterization. ASD repair with transcatheter technique has shown high closure rate. However, coexistence of severe pulmonary stenosis and large defect in atrial septum is rare. When these two problems coexist, the result is i...

Holt-Oram syndrome is an autosomal dominant disorder, characterised by skeletal abnormalities of the upper limb associated with congenital heart defect, mainly atrial and ventricular septal defects. Skeletal defects exclusively affect the upper limbs in the preaxial radial ray distribution and are bilateral and asymmetrical. They range from clinodactyly, absent or digitalised thumb, hypoplastic...
